Ah yeah, that's true, I completely forgot about Rotom-W when I thought of this. I'll leave Whimsicott in because of this and see how it goes.
I think I'm going to change Swampert's EVs as well, and put 156 in Speed and put the ones I've taken away into HP, because I don't think I'm going to see to many M Aerodactyl and M Alakazam (Not saying they on't be used at all, I'm just not to worried about out speeding them), But I can still out speed Timid 252 Speed M Sceptile
